About Salventa
Water security is national infrastructure. We build it here.
Salventa designs and manufactures portable and modular water systems, engineered and assembled in Toowoomba, Queensland, turning uncertain, saline or contaminated sources into safe, reliable supply for defence, mining, agriculture and communities.
Water security, treated as national infrastructure.
Salventa designs and manufactures portable and modular water purification, desalination and wastewater systems, engineered in Australia and assembled in Toowoomba, Queensland. We treat water security as national infrastructure: turning uncertain, saline or contaminated sources into safe, reliable supply, on site and off the grid.
Built here, by people who own the workmanship.
Salventa systems are engineered and assembled in South-East Queensland alongside The Macfab Group, a Toowoomba manufacturer that has built heavy-industry fabrication for the mining, oil and gas, power and agriculture sectors since 2004. Their work spans pressure vessels, pressure piping, structural steel and precision fabrication, the same engineering disciplines a water-treatment system has to be held to.

Her family has worked in the international humanitarian sector for five decades, much of it across South-East Asia, with first-hand understanding of what happens when clean water fails. She has also spent time living within the United States defence community, giving her direct insight into the demands of defence procurement and an understanding of most other sectors Salventa serves. An 8th-generation Australian, she holds an Executive MBA and a Postgraduate Diploma in Dispute Resolution (Bond University). She has built Salventa around Australian engineering excellence and the conviction that clean, secure water is infrastructure worth building to the highest standard.

Guy, CEO, Emu Gully Adventure Education Centre
Read the case studyAt Emu Gully Adventure Education Centre, a Salventa system has supplied safe, reliable drinking water since 2024, independently of the town main, for more than 600 people each week. It has eliminated recurring boil-water alerts and removed the need for more than approximately $100,000 in underground concrete tank infrastructure. All key system components are data monitored and ready for future app-based site management.
